Oil spills: The Exxon Valdez

The Exxon Valdez was an oil tanker owned by the Exxon Corporation (now the Exxon Mobil Corporation after Exxon and Mobil merged in 1999). Laden with 53 million gallons of crude oil, the ship departed the Valdez oil terminal in Alaska for California on March 23, 1989.

However, en route, the Exxon Valdez struck a reef, discharging approximately 11 million gallons of crude oil into the surrounding water.
